Description

Technical Field

[0001] The present invention relates to the technical field of pipeline desilting, in particular to mechanical equipment for desilting urban pipelines. Background Art

[0002] Urban underground pipeline networks are a vital component of modern urban infrastructure, fulfilling critical functions such as transporting water, discharging wastewater, and treating urban stormwater. However, over time, silt and other sediments inevitably accumulate on the inner walls of the pipes. This sediment not only reduces the pipeline's efficiency but can also cause blockages, leading to serious problems such as urban waterlogging.

[0003] In the existing technology, pipeline dredging usually adopts mechanical scraping or high-pressure water flushing. Mechanical scraping has low efficiency and may cause damage to the inner wall of the pipeline. Although high-pressure water flushing can remove some silt, it has limited effect on stubborn silt, affecting the dredging efficiency. Therefore, to address the above problems, a mechanical equipment for urban pipeline dredging is proposed. Summary of the Invention

[0027] Specific examples are given below.

A mud suction pipe 23 for conveying sludge is provided on the inner side of the dredging pipe body 23. A protective pipe 20 is provided on the inner side of the dredging pipe 23. A steam delivery pipe 2 18 for conveying steam is provided on the inner side of the protective pipe 20. A plurality of water delivery pipes 19 for conveying liquid are fixedly provided between the steam delivery pipe 2 18 and the protective pipe 20. A plurality of water delivery pipes 2 22 are fixedly provided on the outer side of the dredging pipe body 23. A nozzle 21 is fixedly provided on the top of the water delivery pipe 22. A support mechanism is provided on the outer wall of the dredging pipe body 1 and the dredging pipe body 2 3 and away from the connecting rod 2.

[0029] This device can clean the silt on the inner wall of the urban pipeline by steam. The high temperature and pressure of the steam can effectively soften and remove the silt on the inner wall of the pipeline, thereby improving the silt removal efficiency. The steam generator, steam delivery pump, water pump, silt suction pump and pusher used in this device are all existing mature technologies. Their structure and use method are not described in detail in this article.

[0030] During operation, the device is placed on the inner wall of the city pipeline, the supporting mechanism is used to make the device contact with the inner wall of the pipeline, and the pusher is used to make the device move on the inner wall of the pipeline to achieve mobile cleaning. In the process of cleaning the inner wall of the pipeline, steam is generated by the steam generator and transported by the steam delivery pump. The generated steam is transported through the steam delivery pipe 2 18. During the transportation process, the steam passes through the connecting valve 17 and the steam delivery pipe 1 16 in sequence until it reaches the inner side of the steam release box 14 and bursts out through the air vent 15 to achieve cleaning. The silt on the inner wall of the pipe is softened and removed. At the same time, the cleaning mechanism arranged at the rear thereof scrapes the silt on the inner wall of the pipe. The scraped silt is guided to the inner side of the silt removal pipe body 2 3 by the cleaning mechanism. As the silt continues to increase, the silt enters the inner side of the mud suction pipe 23, and then the silt is pumped out by the silt suction pump. After the cleaning mechanism cleans the silt, the clean water is pumped to the inner side of the water pipe 1 19 by the water pump. The clean water enters the interior of the nozzle 21 through the water pipe 1 19 and the water pipe 2 22 in turn, and flushes the inner wall of the pipe through the nozzle 21.

[0031] In this device, there are two sets of support mechanisms, located at the front and rear ends of the device, which can maintain sufficient balance during the cleaning process of the inner wall of the pipeline;

[0032] In this device, two groups of cleaning mechanisms are also provided. When the device is advanced, one group of cleaning mechanisms is controlled to move downward, and the other group of cleaning mechanisms is controlled to move upward until it is in contact with the inner wall of the pipe. Thus, in the process of cleaning sludge, the device guides the scraped sludge to the inner side of the two groups of cleaning mechanisms. After the sludge enters the inner side of the two groups of cleaning mechanisms, it enters the inner side of the connecting rod 2. As the device is continuously advanced by the pusher, the sludge continues to increase, and the sludge enters the inner side of the dredging pipe body 2 3 and is discharged through the mud suction pipe 23.

[0033] When the device is pushed backward, the upward and downward directions of the two sets of cleaning mechanisms are opposite to each other, so as to prevent omissions during use of the device. When a pipe part cannot be cleaned in one go, the device can be controlled to clean the same position repeatedly.

[0034] Further, such as Figure 1 and Figure 4As shown, the cleaning mechanism includes a plurality of hinged seats 5 mounted on the loading hoop 4, the tops of the plurality of hinged seats 5 are fixedly mounted with electric spring rods 6, and the ends of the plurality of electric spring rods 6 away from the hinged seats 5 are fixedly mounted with scrapers 7, and the scrapers 7 are provided with notches 32;

[0035] During operation, the loading hoop 4 is used to fix the cleaning mechanism on the dredging pipe body 1 and the dredging pipe body 2 3 respectively. The electric spring rod 6 can be rotated through the hinge seat 1 5 to adapt to the angle change range of the cleaning mechanism when it moves up and down. The electric spring rod 6 can drive the scraper 7 to move up and down. The notch 32 facilitates the adaptation to the bending caused by the expansion and contraction of the scraper 7 when it moves up and down. Since the scraper 7 is annular, the above-mentioned up and down movement is the outward expansion and inward contraction of the scraper 7.

[0036] Further, such as Figure 6 As shown, a steel cord 8 is embedded inside the scraper blade 7;

[0037] During operation, when the electric spring rod 6 drives the scraper 7 to move up and down, the steel cord 8 is equivalent to adding a layer of wire mesh structure in the scraper 7 to fix the inside of the scraper 7 to avoid displacement or damage, thereby improving the strength and stability of the scraper 7. The steel cord 8 can withstand the internal and external forces when the scraper 7 is deformed, limit its deformation, and maintain dimensional stability.

[0038] Further, such as Figure 4 and Figure 5 As shown, a snap-in groove 9 is provided on the inner side of the scraper 7, and a snap-in groove 10 is provided on the inner side of the loading hoop 4. Both the snap-in groove 9 and the snap-in groove 10 are ring-shaped, and an anti-overflow pad 11 is snapped on the inner side of the snap-in groove 9 and the snap-in groove 10.

[0039] During operation, the anti-overflow pad 11 is installed through the clamping groove 2 10 and the clamping groove 1 9. The anti-overflow pad 11 and the scraper 7 in this device are both made of rubber. The anti-overflow pad 11 can ensure that the silt can fall into the inner side of the silt cleaning pipe body 1, the connecting rod 2 and the silt cleaning pipe body 2 3 during the process of moving forward or backward, thereby preventing the silt from overflowing.

[0040] Further, such as Figure 2 As shown, a plurality of connectors 24 are fixedly provided on the mud suction pipe 23;

[0041] During operation, when the device is sucking sludge, the connector 24 on the sludge suction pipe 23 can be connected to the pipeline on the sludge suction pump.

[0042] Further, such as Figure 2As shown, the backs of the multiple scrapers 7 are fixedly mounted with hinged seats 2 12, and the hinged seats 2 12 are hinged with support frames 13. The ends of the multiple support frames 13 away from the hinged seats 2 12 are fixedly connected to the dredging pipe body 1 and the dredging pipe body 2 3 respectively;

[0043] During operation, the second hinge seat 12 is used to fix the support frame 13, and the cooperation between the two enables the scraper 7 to maintain sufficient stability during the cleaning process.

[0044] Further, such as Figure 3 As shown, a connecting valve 17 is further provided on the inner side of the desilting pipe body 1, and a plurality of steam delivery pipes 16 are connected through the connecting valve 17, and a steam delivery pipe 2 18 is connected to the connecting valve 17;

[0045] During operation, when the device is cleaning the sludge on the inner wall of the pipeline, the steam delivery pipe 16 and the steam delivery pipe 2 18 can be connected through the connecting valve 17 to facilitate the delivery of steam. The multiple steam delivery pipes 16 connected by the connecting valve 17 can enable multiple steam release boxes 14 and air vents 15 to burst out steam at the same time, thereby expanding the scope of steam cleaning.

[0046] Further, such as Figure 2 As shown, water pipe 22 extends to the inner side of the protective pipe 20 and is connected to water pipe 1 19; during operation, after the device completes the sludge cleaning action on the pipeline, the inner wall of the pipeline can be cleaned with clean water through the nozzle 21, and the water pump pumps the liquid into water pipe 1 19, and then transports it to water pipe 2 22 through water pipe 19, and the liquid is ejected through water pipe 2 22. In addition, water pipe 19 can also be used to transport anti-corrosion liquid to perform anti-corrosion treatment on the inner wall of the pipeline, thereby extending the service life of the pipeline. The remaining structures of this device can also be used for efficient cleaning of the pipeline before anti-corrosion.

[0047] Further, such as Figure 7 As shown, the support mechanism includes a fixing frame 25 fixedly provided on both the desilting pipe body 1 and the desilting pipe body 2 3, a hinge seat 29 fixedly installed on the fixing frame 25, an electric push rod 30 hingedly connected to the hinge seat 29, a through hole 31 is provided on the fixing frame 25 and above the hinge seat 29, the electric push rod 30 passes through the through hole 31, an adapter frame 26 is hingedly provided on the top of the fixing frame 25, a hinge seat 3 28 is fixedly installed on the adapter frame 26, the hinge seat 3 28 is connected to the electric push rod 30, and a roller 27 is also fixedly provided on the adapter frame 26;

[0048] During operation, two groups of support mechanisms are provided, located at the front and rear ends of the device, which can maintain sufficient balance during the cleaning of the inner wall of the pipeline. The fixed frame 25 is used to load the articulated seat four 29 and the adapter frame 26. The articulation between the fixed frame 25 and the adapter frame 26 can realize adaptive pipe diameter. The expansion and contraction between the fixed frame 25 and the adapter frame 26 can be realized by extending and contracting the electric push rod 30 articulated between the articulated seat three 28 and the articulated seat four 29. The roller 27 can facilitate the movement of the device and the inner wall of the pipeline.
